[boost] Should boost::any::any() be made explicit?

I think the template constructor for boost::any is too general.  I ran into
the problem while trying to overload 

        ostream&operator<<(ostream&, const boost::any&)

If I try to do this, then all types are automatically included in this
overload (because boost::any can be constructed from any type).

I want to provide support for only a couple of types in my overload, and
because of my architecture, I have to have this overload.

Is there any reason not to have boost::any::any() be explicit?
